    <p>I am writing a simple application, an equation system solver. The basic idea behind it is to get the number of variables in the system from user and create that many JTextFields dynamically followed by a button, to solve the system.</p> <p>In my endeavor to achive it, I am struggling to set the vertical scroll bar.</p> <p>What happens is, the layout gets all messed up after the JScrollPane is used.</p> <p>I've used <a href="https://stackoverflow.com/questions/5928514/how-can-i-scroll-my-jframe-using-the-jscrollbar">this</a> as a guide and tried doing it this way, with VERTICAL_ALWAYS AND HORIZONTAL_NEVER, but it doesn't work.</p> <p>The controls are placed side ways, instead of one-after-the-other from top to bottom.</p> <p>How to achieve this ?</p> <pre><code>public class SolverUserInterface implements ActionListener{ private JFrame solverUI; private JPanel panel; private JLabel lbl[]; private JTextField eq_Fields[]; public SolverUserInterface(int Count) { // TODO Auto-generated constructor stub solverUI = new JFrame("Solver"); solverUI.setSize(405, 137); solverUI.setResizable(false); Dimension dim = Toolkit.getDefaultToolkit().getScreenSize(); solverUI.setLocation(dim.width/2-solverUI.getSize().width/2, dim.height/2-solverUI.getSize().height/2); solverUI.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); panel = new JPanel(); panel.setLayout(new FlowLayout()); lbl = new JLabel[Count]; eq_Fields = new JTextField[Count]; for(int i = 0; i &lt; Count; i++){ lbl[i] = new JLabel("Equation "+(i+1)+" : "); eq_Fields[i] = new JTextField(26); panel.add(lbl[i]); panel.add(eq_Fields[i]); } JButton btnSolve = new JButton("Solve Equations!"); panel.add(btnSolve); btnSolve.addActionListener(this); /*This is the part concerned*/ JScrollPane jp = new JScrollPane(panel, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER); solverUI.add(jp); solverUI.revalidate(); } public void ShowUserInterface(){ solverUI.setVisible(true); } @Override public void actionPerformed(ActionEvent arg0) { // TODO Auto-generated method stub } } </code></pre>

    1. COUsually, with this kind of question, you have better to insert the codes (not all but the specific code that you have a problem with it). See the [SSCCE](http://sscce.org/) and this [question checklist](http://msmvps.com/blogs/jon_skeet/archive/2012/11/24/stack-overflow-question-checklist.aspx).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
